IBATTERY-POST SEAL.

Application filed August 27,-1924. Serial No. 734,392.

It is Well known thatit'is diflicult to seal the top of a battery overthe battery plates and liquid so as to prevent leakage around.

the posts or terminal members. This is due in large measure to the factthat the tops or covers, commonly used been down on the connecting baror base of the post and to which the plates are attached and these connecting bars or bases are not always straight or so positioned that thetop will rest squarely and snugly in place, but are tilted slightly. Theobject of my invention is to correct this defect and to provide aconstruction and arrangement which will make it possible to use thewell-type of top or cover and to get a perfect seal. I do this byproviding the terminal post with an annular collar or flange at a spaceabove the base or connecting bar to which the plates are attached andthen in providing a gasket above said flange or collar to receive thetop or cover. I also prefer the well-type of cover sothat the lower orinner end of said well rests around the post and upon said gasket andflange, and then provide a taper fit nut for securing the top or coverto the battery post. In order to fully describe my invention, I haveillustrated the same on the accompanying sheet of drawings, which I willnow describe. In the drawings,

Figure 1 is a vertical sectional view through the top portion'of abattery em- I I bodying my invention.

In the embodiment of my invention here shown for illustrative anddescriptive purposes, 1, designates the jar, 2 the battery plates,attached to the base or connecting bar, 3, of a battery post orterminal, 4. Said gostis provided'with an annular collar or ange, 5, ashort distance above the base, or connecting bar 3, which carries theplates. The top or cover is designated 6, and is pro vided with two wellopenings, as 6 6", of

tapering form, so that when placed over the posts, 4, they rest downupon gaskets 7, 7, on said posts, over said collars, 5, and a shortdistance above the connectin bars or bases 3, 3, as clearly illustrated.packing, 8, is

placed around each terminal post, 4, Within the well of the cover, 6,and a-taper fit nut, 9, is screwed onto the post, down in the Well witha taperfit, thus perfectly sealing the joint between the c0ver,or top,and the post or terminal which supports the battery plates.

y thus providing an annular shoulder or collar around'the terminal postofthe battery plates, above the base or supportin bar for the plates, Iavoid the necessity o the top or cover 6, resting down on the said baseor connecting bars, 3, 3, and make possible a better fit and a betterseal.

I do not'limit my invention to the details 'of the application as shownand described for explanatory purposes, exce t as I may be limited bythe hereto appen ed claim. I claim:

cover therefor having a well opening therethrough of tapering form, aterminal post having an annular collar formed thereon to engage withtheinside of said cover as said post is inserted up through said wellopenmg, a laterally projectlng base at the lower end'of said post andbelow said annular collar, a battery plate connected to said base, saidpost being threaded intermediate its ends, a taper fit nut threadedinternally and adapted to screw down on said terminal post, the outerperiphery of said nut being in direct taper fit with the well-opening towedge thereinto, and a packing placed in the bottom of said well opensing around said terminal post and below said taper nut but not extendingabove said nut, whereby as saidnut is screwed down into said wellopening on said terminal post, the lower end of said nut forces saidpacking around the opening through which said terminal post is located,substantially in the manner shown and described.
